Polyaluminum chloride can be used in the purification of domestic water, industrial wastewater treatment, urban sewage treatment, and has very good effects on sludge dewatering after sewage treatment. Therefore, polyaluminum chloride is widely used in the water treatment of various industries by adding it to the treated sewage to achieve the effect of clean water.<\/p>\n
After adding polyaluminum chloride to water, it can reduce the stability of colloidal particles in the water. By destroying the colloidal particles, it achieves the effect of adsorption, coagulation, trapping, and precipitation by polyaluminum chloride<\/a> to remove pollutants from the water.<\/p>\n In the water treatment of various industries, due to the significant differences in industrial wastewater, it often requires corresponding experimental trials to obtain the accurate dosage of polyaluminum chloride and the specific usage method based on the trial results. Because the wastewater from various industries is complex, polyaluminum chloride<\/a> alone is sometimes difficult to achieve the desired water treatment effect, and it needs to be combined with corresponding coagulants for treatment. For example, after adding polyaluminum chloride, an appropriate amount of polyacrylamide can be added to the treated sewage to achieve the best water purification effect through the coagulation effect of polyaluminum chloride<\/a> and the coagulation aid effect of polyacrylamide.<\/p>\n
